# ==== Purpose ====
|
|
#
|
|
# This file is an engine to process commands like
|
|
# rpl_mixing_engines.inc. It has the same set of commands, and in
|
|
# addition the extra command 'recovery'. The 'configure' and 'clean'
|
|
# commands are also extended version of the same commands in
|
|
# rpl_mixing_engines.inc.
|
|
#
|
|
# ==== Usage ====
|
|
#
|
|
# --let $commands= command1 command2 ...
|
|
# --let $database_name= name
|
|
# --let $failure= d,debug_flag
|
|
# [--let $verbose= 1]
|
|
# --source include/rpl_mixing_engines.inc
|
|
#
|
|
# Parameters:
|
|
#
|
|
# $commands, $database_name, $verbose
|
|
# See rpl_mixing_engines.inc.
|
|
#
|
|
# $failure
|
|
# This debug symbol will be set. See the implementation for
|
|
# details.
|
|
#
|
|
# ==== Implementation ====
|
|
#
|
|
# This file has its own code for 'configure' and 'clean'. For other
|
|
# commands, this file first configures the server according to
|
|
# $failure, and then delegates the commands to rpl_mixing_engines.inc.
|
|
|
|
#
|
|
# Creates tables used throughout the test and changes the type of the
|
|
# mysql.slave_relay_log_info to Innodb.

#
